The roundabout kerbing has suffered wear and tear from heavy vehicles being driven across the top when negotiating the roundabout.

Concrete edging had cracked and broken away, presenting a potential traffic hazard.

The Roads and Traffic Authority chose to replace the concrete edging with a rubberised compound able to withstand the high volume of heavy traffic passing over the surface.

Glen Innes Municipal Council director of Works and Infrastructure Ralph Stoeckeler said the damage to the kerbing was caused by heavy vehicles cutting across the roundabout.

"The roundabout construction causes drivers of heavy vehicles to cut across the edges of the roundabout rather than stay on the roadway as they pass through,” Mr Stoeckeler said last week.

"Council reported the problem to the RTA some time ago and they are now in the process of repairing that damage.”

Work started at the beginning of last week and was expected to take a little over one week to complete.

There was believed to have been minimal disruption to traffic during the roadworks.
